seeing how nightmare moon was blasted to the moon, and she fought celestia so by power scaling nightmare moon should be solar system level

so a talking unicorn with wings that can teleport, turn into smoke and shoot magic beams that wouldn’t even scratch raditz, the most weakest villain in dbz vs a giant humanoid demon monster?  
you’re kidding you’re kidding right? seriously here’s what would really happen: Vaatu: really this is my opponent? a fucking unicorn with wings? are people trying to make me look pathetic? nightmare moon: you dare insult me little foal? I will kill- Vattu:stabs nightmare moon with tentacles then proceeds to rip her to pieces with his claws Vaatu: pathetic, truly pathetic.  
seriously guys this is like putting a normal person against a GOD, it’s completely one-sided.

That can be summed up with lolfiction.  
Dragon Ball characters are planet to solar system level in destruction. Yet their ki blasts don’t destroy the planet in one shot.
 
Same goes for Base Gurren Lagann. At the end of the first part of that series, Gurren Lagann has been calc’d to be at 5.7 exatons (high continent level destruction) yet it doesn’t destroy any continents.
 
Focused energy. Also, plot armor for the planet they’re on. So yeah.
 
Also, not usable in a fight? You do know how much energy it takes to move a celestial body like that, right? That means Celestia and Luna’s magic is powerful.

And yet, when in a fight with a peer of similar power that she is actively trying to kill, the best Nightmare Moon can bring to the fight is lasers that only leave potmarks in what they hit, at best.
 
Granted, Celestia surviving a hit by ones gives the alicorns a decent durability feat( a normal human wouldn’t live through that), it isn’t exactly something that says that their ability to move the sun/moon is something usable in a fight, otherwise they would, you know, use it.

@Karna
 
Pft… Hahahahaha!
 
Try harder.
 
Read the spoilers in that calc. Boom shakalaka. Amy Keating Rogers confirmed that the MLP!Sun is the same size as ours. Ain’t that a shame.
 
So… Result of this match: Dark Avatar Unalaq tastes the curb. Or gets vaporized. Either one works.

@Karna  
Okay, but the victor depends on which world they’re in.

You’re seriously trying to use a Outskirts Battledome wiki as a source?
 
That’s just cute.
 
Too bad the season 4 premier punted them right the fuck out of the “solar system level” category to “street level” category for destructive potential with the half-day/half-night thing.
 
My Little Pony’s sun isn’t a giant nuclear reactor, and its moon isn’t a big ass rock revolving around the planet. The fact that having the moon in the sky at the same time as the sun means half the sky is night proves that. You can extrapolate nothing from raising/lowering the sun/moon now other than the fact that they decide when its day and when its night.
 
Try again.

@Background Pony #53CE  
In fact, let’s do a run down on what these two are bringing to the table:
 
Nightmare Moon: energy blasts, incorpreal transformation, ability to control the night, gains her power from the moon and has legions of Nightmare Forces at her disposal.
 
Vaatu/Unalaq: energy blasts, can corrupt spirits into dark spirits, tentacles, can summon up vines, controls legions of dark spirits, waterbending (which becomes more powerful depending on the phases on the moon) and spiritbending.
 
Now, in regards of Nightmare Moon just dropping the moon on him. That… would not work out for three reasons.
 

@Background Pony #53CE  
Let’s keep in mind it’s both Unalaq and Vaatu. We saw what Vaatu is capable of: energy blasts, can summon up vines and corruption of spirits into dark spirits. We don’t really know what else he’s capable of.

@Karna
 
You were saying?
 
Not wank. And no, I didn’t make that profile since I can’t edit that wiki. The Dark Avatar didn’t show anything impressive apart from making a bit of a dent on a small hill. That’s not too high, though.

@Background Pony #53CE
 
Your wank and furious denial of what was actually in the show is hilarious.
 
The sun and moon and My Little Pony have absolutely nothing to do with their real life counterparts, considering that having them both in the sky at once results in half day, half night.
 
If Nightmare Moon could drop the moon on somebody in a fight, she would have done it.
 
The extent of Nightmare Moon’s battle abilities are pretty much some not very impressive lasers, teleportation, and turning gaseous.

Only one of them is close to planet level destruction. And it’s not Dark Avatar Unalaq.
 
Nightmare Moon wrecks him by dropping The Moon on him.

Vaatu realizes that Unalaq is boring so he fuses with Nightmare Moon and disintegrates Unalaq.
 
Vaatu Moon wins!

Unalaq/Vaatu would win easily. Doesn’t stop Unalaq from being one of the most boring Avatar villains though.

I’m gonna have to give this one to Unavaatu.

For a moment, I thought that was Iris from the Gamera series.

“Grrrrrr”  
“Grrrrrr”  
(tea party)  
Luna/Vaatu wins  
FRINDSHIP!

ruler of darkness vs spirit/avatar of darkness
 
Could be pretty interesting
